SPECIFICATION forming part of Letters Patent No. 705,930, dated July 29,1902.

Application filed March 29, 1902.

T0 all w/wm/ it may concern: Y

Beit known that LAUGUST JOSEF JAEGER, a citizen of the United States,residing at Phillips, in the county of Price and Statepof Wisconsin,have invented certain new and useful Improvements in Saw Clamps, Y ofwhich the following is a full, clear, and exact description.

My invention relates to saw-clamps, more particularly of the kind usedin securing saws in position to be sharpened or otherwise operated upon.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective view of my device ready to be applied to atable or similar structure. Fig. 2 is a plan view of the structure,showing the saw and clamping-plates in position. Fig. 3 is aperspectiveview, somewhat reduced, showing a pair of my devices in use.

` The device is preferably used in connection with a table 1. In theforest, where no such table is available, one may be" improvised bysecuring a board upon the tops of two stumps. The saw-clamp comprises asubstantially S-shaped frame 2,7the respective ends 3 and of whichterminate in screw-eyes 5 6. A jaw 7, provided with a straight and iiatsurface, is integrallymounted upon the frame. Screw members 7 8 engagethe screw-eyes 5 and 6, respectively. Movable plates 9 10 are mountedupon the screw members and are free to approach and recede from the flatsurfaces 7 and 8, respectively. Bosses 11 and 12 upon these plates serveas bearings for the screwmembers. The plates 9 10 are bifurcated at 1314, so asto engage the slideways 3 13a.' The flat boards 15 16 are ofsubstantially the same conformity as the saw-blade 17.

My device is used as follows: A saw is placed between the boards, theclamps are SerialNo. 100,564=. (No model.)

secured upon the table /as indicated in Fig. 3, the boards containingthe saw are placed between the jaws 7 and the plates 9, the screws areall tightened, and the operative proceeds to file the saw in the usualmanner. 5o

I do not limit myself to the particular shape and size of boards shown,for obviously these boards may be 'made of any shape and size, so as toconform to the shape and size of any ordinary saw used by hand.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A saw-clamp, comprisinga substantially S-shapedmember terminating at each of its ends in a screw-eye, and provided witha slide disposed adjacent to leach of said eyes, a screw member engagingeach of said eyes, and a iat plate mounted transversely upon each ofsaid screw members, and provided with a bifurcated edge for straddlingone of said slides, being guided thereby.

2. A saw-clamp, comprising a frame pro'- vided with a depending bracket,a screw-eye integrally vmounted upon said bracket, a screw engaging saidscrew-eye, a plate mounted upon said last-mentioned screw, a jawintegrally mounted upon said frame opposite said last-mentioned plate, ajaw integrally mounted upon said frame at right angles with the jawfirst mentioned, a bracket integrally mounted upon saidframe andprovided with a screw-eye and with a slide, a screw revolubly mounted insaid screw-eye, and a plate provided with an aperture engaging saidscrew, and with a bifurcated end for straddling said slideway. t Intestimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

AUGUST JOSEF JAEGER.
